how to have dripping water when object comes out of water
Edit: TLDR: Add another object that emits additional fluid while the object is being lifted out of the liquid.

Duplicate the cube, scale the duplicate up by a teeny bit, and change that into a liquid inflow object.

For the additional inflow object:


Add a solidify modifier with a really small value. If the solidify value is too large, you're going to get an unrealistically thick layer of fluid.
Delete any faces you don't want to have the fluid emitted from, notably faces such as the bottom.
Add keyframes so that the emitter only emits for a few frames while lifting the object out of the water. You'll have to play around with how long/when you want it to do so.
